Bhagavad Gita 18.73 is Chapter 18, Verse 73, in Moksha Sanyasa Yoga (Liberation). Below are the Sanskrit text, a transliteration, a plain-English translation and an explanation.
arjuna uvāca naṣṭo mohaḥ smṛtir labdhā tvat-prasādān mayācyuta sthito 'smi gata-sandehaḥ kariṣye vacanaṁ tava
"Arjuna said: My delusion is destroyed, and I have regained my memory through Your grace, O Achyuta. I stand firm with doubts gone. I will do Your word."
What This Means:
Arjuna declares: My confusion is gone, my true understanding has returned by Krishna's grace. I am now firm, doubt-free, and will follow Krishna's instructions.
Going Deeper:
'Nashto moha' - delusion destroyed. 'Smritir labdha' - memory regained - recollection of his true nature. 'Tvat-prasadat' - by Your grace. 'Achyuta' - unfailing one. 'Sthito asmi' - I stand firm. 'Gata-sandeha' - doubts gone. 'Karishye vachanam tava' - I will do Your word. Complete transformation from Chapter 1's despair to resolute clarity.
How To Apply This:
This is the fruit of true teaching: delusion destroyed, true nature remembered, firmness established, doubts resolved, ready to act. Seek this clarity.
Where this verse sits
In 18.72 Krishna asks whether Arjuna has listened with a concentrated mind and whether his delusion born of ignorance has been destroyed. Verse 73 is the answer, and it is Arjuna's last word in the Gita. Everything after it belongs to Sanjaya, the narrator, who closes the book in 18.74 to 18.78. The verse therefore has to be read against where Arjuna started: 1.47, where he sat down in his chariot with his bow dropped and his mind overwhelmed with grief, and 2.7, where he asked to be taught.
What the words say
Nashto mohah, 'the delusion is destroyed', answers Krishna's question in his own words. Smritir labdha, 'memory is regained', is the more interesting phrase: Arjuna does not say he has learned something new but that he has remembered, and Shankara glosses the memory as knowledge of the self, the recognition of what was always the case. Tvat-prasadat, 'by your grace', attributes the change to the teacher rather than to effort. Achyuta, 'the unfallen one', is the name he chooses. Gata-sandeha, 'with doubt gone', and sthito 'smi, 'I stand', describe the result, and karishye vachanam tava, 'I will do your word', is the decision.
A common misreading
The verse is sometimes read as submission, as if Arjuna had simply agreed to obey. The framing argues otherwise. Krishna's instruction in 18.63, before the closing verses, was 'do as you wish'; Arjuna's 'I will do your word' is what a free person says after understanding, not what a cornered one says. Arjuna's last words are a decision to act, and the action is the one he could not take in chapter 1; his final reply resolves his own first refusal.
